Total and CNOOC found 37 metres of net gas and condensate in a well drilled to a final depth of 5,056 metres.

Further drilling and testing will be carried out to assess resources and the productivity of the reservoir.

The latest news comes after Total announced a major gas discovery on the Glendronach prospect on the west of Shetland in September last year.

Kevin McLachlan, senior vice president exploration at Total, said: "Following the recent Glendronach discovery, west of Shetland in the UK, Glengorm is another great success for Total in the North Sea, with results at the top end of expectations and a high condensate yield in addition to the gas.

"Our strong position in the region will enable us to leverage existing infrastructures nearby and optimise the development of this discovery.

"Glengorm is an achievement that demonstrates our capacity to create value in a mature environment thanks to our in-depth understanding of the basin."

Total holds a 25% working interest in the Glengorm discovery, alongside CNOOC Petroleum Europe Limited, a wholly-owned subsidiary of CNOOC Limited (50%, operator) and Euroil, a wholly-owned subsidiary of Edison E&P SpA (25%).

He said: "This is a major find and a great example of partner companies, CNOOC International, Total E&P and Edison working together to explore and unlock the potential of the UK Continental Shelf (UKCS).

"Glengorm was a challenging prospect to drill, however the combined determination and perseverance of the partners has paid off.

"The location of the discovery, in the central North Sea, also provides a valuable opportunity to make use of the UKCS' extensive infrastructure network.

"Coming so soon after the Glendronach discovery in September, Glengorm is a major milestone towards adding another generation of productive life to the UK North Sea and realising the ambition of Vision 2035."

Environmental campaigners said the discovery was bad news for the climate and called for a transition away from fossil fuel development.

Caroline Rance, Friends of the Earth Scotland climate campaigner, said: "We've known for years that we need to leave fossil fuels in the ground if we're to tackle climate change.

"But just months after the Intergovernmental Panel on Climate Change's stark warning on the climate crisis, it's clear that big oil and gas companies still aren't listening.

"It's a disgrace that oil and gas exploration is still going ahead in the seas off Scotland."

However, Scotland's Energy Minister, Paul Wheelhouse, said: "I welcome this announcement which highlights the significant potential for oil and gas which still exists beneath Scotland's waters.

"Scotland's offshore oil and gas industry has an important role to play with up to 20 billion barrels of oil equivalent remaining under the North Sea and in the wider basin and discoveries such as this help to support security of supply as we make the transition to a low carbon energy system.

"The Programme for Government reinforces our commitment to the sector, recognising both the significant opportunities remaining and our continued support of Maximising Economic Recovery from the North Sea.
